Title: Improvement in automatic change speed gears
IPC: F16H61/02
Filed: 1934-07-23
Abstract: 427,856. Variable-speed gearing. JONSSON, G. E., Huddinge, Sweden. July 23, 1934, No. 21497. [Class 80 (ii)] An automatic change-speed gear for motor vehicles and other purposes including a centrifugal clutch 4 which engages at a predetermined speed and one or more uni-directional clutches 8, 8<a> to permit the lagging behind of the gear or gears not transmitting power, has a manually-operable friction clutch 4<a> adapted to perform a change from the gear of lowest order to the gear of the next highest order. The friction clutches 5, 4<a> are operable by levers 7, 7<a> respectively under the control of a common member such as the ordinary clutch pedal, the release of which allows first the clutch 5 and afterwards the clutch 4<a> to engage. The plate clutch 5 and the centrifugal clutch 4 have a common member x connected to the first-motion sleeve 9. In operation, when a clutch member 17 splined on the driven shaft 2 has been moved by the gear lever into engagement with the free-wheel roller clutch 8, and the clutch pedal partly released, the clutch 5 is engaged and the first speed operates through gears 10, 13, 15, 12. The complete release of the clutch pedal causes the engagement of a plate clutch 4<a>, the second speed being taken up through gears 10, 13, 14, 11 and the clutch 8 overrunning. A further increase in speed of the driven shaft causes the centrifugal clutch 4 directly connecting the driving and driven shafts to engage automatically. Backward movement of the member 17, which is constructed as a gear wheel brings in the reverse drive.

Abstract: 1427656 Superconductive circuits INTERNATIONAL BUSINESS MACHINES CORP 15 May 1974 [29 June 1973] 21506/74 Heading H3X A superconductive OR circuit comprises three gates, GATE 1 to GATE 3, Fig. 1, each gate consisting of two parallel branches 10, 12 which include respective Josephson junction devices JA, JB, the gates GATE 1 and GATE 2 each passing a current Iw through one or other of their branches in accordance with the zero or finite voltage state of the junctions as determined by an "0" input or a "1" input applied to respective junction gate circuits 18, 20, and the conductive state of the two gates together determining the branch in GATE 3 through which the current Iw is permitted to pass. In GATE 3 the passage of current Iw through Josephson junction JA3 denotes an OR relationship of the inputs to GATES 1 and 2, while the alternative passage of current Iw through junction JB3 denotes a NOT OR relationship. The gates branches are arranged so that each serves as a gate circuit for a respective Josephson junction junction device JC, JD which serves as a sensor of current Iw. Sensors JC1 and JC2 are connected in series as shown in Fig. 4. If either or both sensors are in the finite voltage state due to the presence of current Iw in one or both paths 10a, 10b of GATES 1 and 2, an inhibiting current pulse output ISN is applied over a damping resistor RB to the gate circuit 20c of Josephson junction device JB3 in GATE 3. Current Iw then passes through path 10c, and the OR relationship of "1" inputs is signalled by sensor JC3. Sensors JD1, JC2 in the other branches of GATES 1 and 2 are connected in parallel to the gate circuit 18c of Josephson junction device JA3 in GATE 3, the current path including a damping resistor RA. If both sensors JD1, JD2 are in the finite voltage state due to simultaneous "0" inputs, the current Iw passes through paths 12a and 12b of GATES 1 and 2, and an inhibiting current pulse ISN causes Josephson junction device JA3 to attain its finite voltage state. Current Iw in GATE 3 then passes through branch 12C which is indicated by sensor JD3 as a NOT OR relationship.

Abstract: 1, 040, 212. Tube mills; grinding cement. F. L. SMIDTH & CO., A.S. May 20, 1964 [May 31, 1963], No. 21931/63. Heading B2A. A method of producing cement ready for packing into bags comprises grinding cement clinker in a mill, cooling the ground cement after it leaves the mill by carrying it in an upward current of air, separating it from the air when cooled and delivering at least some of the ground separated cement to a discharge conveyer. Ground cement from a mill 1, Fig. 1, is conveyed by means of a pipe 8 and warm conveyer 9 to a cooling riser pipe 11 the lower end of which is open to the atmosphere. The suspended cement particles are separated from the air in a cyclone 13 and passed through a pipe 27 to the feed tank of a discontinuous pneumatic conveyer 30. The air heated by the cement is conveyed by a fan 12 to a dust filter 16 the separated dust from which is caught by worm conveyer 18 and led into conveyer 9. Pipe 8 has an extension 20 through which pass water vapour and cement particles under vacuum produced by fan 21. The dust is separated in cyclone 22 and led to conveyer 9 while the air is conveyed to the filter 16. In a modification, the pipe 8 opens into the bottom of an elevator 32, Fig. 3, which raises the cement so that it flows down through a pneumatic conveying trough 33 into an air separator 34 in which it is divided into two fractions. The coarse fraction is conveyed via pneumatic trough 37 to the inlet end of the mill for further grinding. The fine fraction is conveyed via worm conveyer 41 to the pipe 11. Conveying air is sucked in through a pipe end 45. Dust from the top of elevator 32, from trough 33 and from trough 37 is passed through pipes 48, 49, 50 respectively which lead to a common pipe 47 connected to the filter 16. In another modification, Fig. 4 (not shown), two filters are provided and the common pipe is connected to the riser pipe instead of the filter. In a further modification, Fig. 5 (not shown), cement from the mill is fed to the riser pipe the upper end of which is connected to a cyclone from which air containing fine dust is conveyed by a fan to the filter while coarser cement is passed to an air separator where the cement is divided into two fractions, the finer fraction being carried by a worm conveyer to the feed tank of the pneumatic conveyer while the coarser fraction is returned to the inlet end of the mill for further grinding.
